Starting from this lesson, we will share how to use MicroBit to create a control system for a three-level elevator.
To complete such a small project of a three-level elevator, you need to be familiar with the basic usage of MicroBit and purchase some component materials.
If you are not familiar with MicroBit, you can log into the DF forum to check out Teacher Jin’s basic course on MicroBit. The URL is as follows:

In this lesson, we mainly introduce such a small system and briefly explain the basic principle of transistors.
Required components:
1. The most important component used in the elevator project: Slot-type optocoupler

The MicroBit three-level elevator course can be considered a relatively simple small project. Everyone can also complete such a project based on their own ideas, and if there are any unclear points, feel free to contact me for discussion.
